Of course. There is no room for both anyway.

Thanks Ron. Now I understand how it works. Everything else looks good. The trust bearing was there and if fair shape... little rust on it. Only the bushing worn out.

My bushing is worn out. Could you understand where the seal is made in the clutch? I couldn't get that other than maybe massive flow.

Thank you Ron. This bushing I draw, looks right to you as dimensions please?

I will have them made out of tuffkast I think. I needed only the dimensions so I can replace in same day. Do you have by any chance a drawing with the original Allison bushing? Maybe some grooves for lubrication in there? Thank you.

So a "washer" 0.335" thick with an ID of 1.992" and OD of 2.920" instead of that bearing ? Thanks

Is that Allison bushing or DIY? What are the dimensions? Thanks.

So I got a 0-350 psi gauge. Gauge come with the needle at 35 psi out of the box, so no accurate, but shows something. C7 on "mode" shows about 30psi. Main about 190 psi when Mode Off. When I press Mode, Main pressure drops to about 110 psi. To me, this looks clearly like a big leak in C7 piston...

Ok. I bought off e-bay another valve assembly. It looks brand new, never installed. Coil 3.4 ohms. I got also a PWM generator. 0-30 V and 0- 30 mA. I hooked the PWM generator to the solenoid and I couldn't hear or see a thing. Looks like my cheap voltmeter can show the voltage if it is there...

I checked with a hydraulic gauge (0-3500 psi) C7 and MAIN in the attached picture. The needle won't move at all in neutral, or in gear or in MODE. I confirmed that oil comes out the hose to purge the air. A 0-500 psi gauge would be more adequate but still no pressure at all. I took again the...

You explain this to me in a previous post but couldn't understand and make correlations because I was looking on wrong diagrams. Now with the diagram you just posted makes more sense. Thank you. I took for 4 years industrial electronics classes in college, but that was 10years ago and never...

I miss the knowledge to differentiate a coil from a lamp haha and some more. Thanks.

Ron,I look over the digram in the attached picture: I see solenoid hooked up to D1 and to the ground so I if I hook up a wire to D1 and another one to the ground, in my understanding I should have an appropriate signal. What I miss? Thank you.

So maybe the TCU is reading impedance rather than resistance ? I will definitely do the bulb test tomorrow! I have a dielectric grease spray. Do you consider a good idea to spray contacts with that or not?

I was thinking the signal is DC, some square wave, from 0V to whatever 12v, and that gives % of duty cycle. I had no idea the signal is AC. I never set up the voltmeter below 20v DC and AC can measure only 200 and 300V, so no way to see anything. Looks like I have to invest in some more up to...
